Abstract - Shell and Tube Heat Exchanger in which it is
Fixed Tube-sheet and Counter Flow Type Heat Exchanger. Here, Shell side fluid is cold water and tube side fluid is hot water .Cold water is cold fluid and hot water is hot fluid. I do Thermal Designing STHX due to the problem of Less Heat Transfer rate and Cost is very high and also will do analysis of corrugated tube and compare with existing plain tube. I will make prototype experiment model of shell and tube heat exchanger in which plain and corrugated tube is use one after one and take reading for thermal analysis calculation. Here shell is made by still and tube is made by aluminium. After doing experiment work I will get different comparative result for both plain tube and corrugated tube. Here we show that use of corrugated tube effectiveness increase and pressure drop decrease. So the pumping cost decrease and heat transfer rate increase. Shell and Tube Heat Exchangers are used as process heat exchangers in the petroleumrefining and chemical industries. It is used as steam generator, condensers, boiler feed water heater, and oil coolers in power plant. Key Words: Heat transfer, Effectiveness, corrugated tube, Plain Tube 1. INTRODUCTION A shell and tube heat exchanger is a important of heat exchanger device. It is the most useful type of heat exchanger in oil refineries and other large chemical processes and is best use for higher-pressure instruments and area to volume ratio higher than other heat exchanger. As their names explain, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid flow through the tubes, and another fluid runs over the tubes (through the shell) to transfer heat between the two fluids. The set of tubes is called a tube bundle, and may be composed of several types of tubes: plain, longitudinally finned, micro fin etc. Shell and tube heat exchanger is type of heat exchanger an according to design and construction form TEMA standard.
It can be planed for almost any moral obligation to work with a very wide range of pressure & temperatures.
It can be construct by using many materials like Mild steel, Stainless steel etc
Many suppliers are available.
1.2 Scope of Shell and Tube Heat Exchanger (1)
Temperature Range Maximum 500oC or even 600oC, minimum -100oC
(2)
High Pressure Shell 300 bar, Tube 1400 bar
1.3 Construction and Working of Shell and Tube Heat Exchanger A shell and tube heat exchanger is a rank of heat exchanger designs. It is the most ordinary type of heat exchanger used in oil refineries and other large chemical processes, and is retinue for higher-pressure applications. As its name implies, this type of heat exchanger to be made up of a shell (a large pressure vessel) with a bundle of tubes interior it. Shell and tube heat exchangers are designed by the Tabular Exchanger Manufactures Association (TEMA) Standard. In a single pass shell and tube heat exchanger; the fluid enter in one end of tube and out at the other end of tube.
